DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD7554A, 7554A(A)  
4-BIT SINGLE-CHIP MICROCOMPUTER  
DESCRIPTION  
The µPD7554A is a product of the µPD7554, 7564 sub-series which is a 4-bit single-chip microcomputer with a  
small number of ports in a small package, which is enabled to operate even at the super-low voltage of 2.0 V so  
that it is optimized for handy-type systems operating with dry cells. The µPD7554A is a low-order model in the  
µPD7500 series (µPD7554A only).  
This device incorporates a serial interface, and serves as the sub-CPU for a high-order model of that series or  
the 8-bit microcomputer. It is optimized for distributed processing of the system.  
The µPD7554A has outputs to directly drive a triac and LEDs and allows selection among many types of input/  
output circuits using their respective mask options, sharply reducing the number of external circuits required.  
Details of functions are described in the User’s Manual shown below. Be sure to read in design.

APPLICATION  
★
µPD7554A  
: Sub-CPU including handy-type system, PPC, printer, VCR, audio equipments, etc.  
µPD7554A(A) : Automotive and transportation equipments, etc.  
The quality level and absolute maximum ratings of the µPD7554A and the µPD7554A(A) differ.  
Except where specifically noted, explanations here concern the µPD7554A as a representative product.  
If you are using the µPD7554A(A), use the information presented here after checking the functional differences.  
The information in this document is subject to change without notice.  
The mark ★ shows major revised points.
